Enhanced magnetization in sputter-deposited copper ferrite thin films

Copper ferrite thin films have been prepared by RF sputtering on quartz substrates. By following successive heating and quenching, it was possible to obtain the films, which showed cubic phase in X-ray diffraction. The grain size was found to be similar to 30 nm. The magnetization was observed to be of the order of 3000 G with a coercivity of 480 Oe. (C) 2002 Elsevier Science B.V. All rights reserved.
